Neo managed to tear a third of his tail fin off right at its base this morning and I'm not sure how (if?) to treat him. His behavior/appetite hasn't changed at all, so he seems to be doing okay, but I want to be doing all I can to help him. I did go ahead and add some additional stress coat to his water. Suggestions??
